Umesh YadavandPeter Tripp 4c411b9fc8 language_models: Make JsonSchemaSubset the default tool_input_format for the OpenAI-compatible provider (#34921)
Closes #30188
Closes #34911
Closes #34906

Many OpenAI-compatible providers do not automatically filter the tool
schema to comply with the underlying model's requirements; they simply
proxy the request. This creates issues, as models like **Gemini**,
**Grok**, and **Claude** (when accessed via LiteLLM on Bedrock) are
incompatible with Zed's default tool schema.

This PR addresses this by defaulting to a more compatible schema subset
instead of the full schema.

### Why this approach?

* **Avoids Poor User Experience:** One alternative was to add an option
for users to manually set the JSON schema for models that return a `400
Bad Request` due to an invalid tool schema. This was discarded as it
provides a poor user experience.
* **Simplifies Complex Logic:** Another option was to filter the schema
based on the model ID. However, as demonstrated in the attached issues,
this is unreliable. For instance, `claude-4-sonnet` fails when proxied
through LiteLLM on Bedrock. Reliably determining behavior would require
a non-trivial implementation to manage provider-and-model combinations.
* **Better Default Behavior:** The current approach ensures that tool
usage works out-of-the-box for the majority of cases by default,
providing the most robust and user-friendly solution.


Release Notes:

- Improved tool compatibility with OpenAI API-compatible providers

Licensing

License information for third party dependencies must be correctly provided for CI to pass.

We use cargo-about to automatically comply with open source licenses. If CI is failing, check the following:

  • Is it showing a no license specified error for a crate you've created? If so, add publish = false under [package] in your crate's Cargo.toml.
  • Is the error failed to satisfy license requirements for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the accepted array in script/licenses/zed-licenses.toml.
  • Is cargo-about unable to find the license for a dependency? If so, add a clarification field at the end of script/licenses/zed-licenses.toml, as specified in the cargo-about book.
